摘要：

The macroscopic properties, microscopic morphology and corrosion resistance of Hastelloy C276-reinforced coatings produced by laser cladding under varied laser scanning speeds on the surface of AerMet100 steel were investigated. The coating quality was found to be good with no visible cracks. With the increase in scanning speed, the coating dilution rate showed a trend of dropping and then increasing. The increased scanning speed also impacts the number of pores in the coating and refines the metallographic organization. The electrochemical data reveal that the coatings outperform non-reinforced AerMet100 steel in terms of corrosion resistance, with the greatest results coming from Sample #3 (scanning speed of 14 mm/s), which is the consequence of the combined effect of dilution rate, porosity, and grain size.
